Because they are indeed part of a Jewish Mafia. Nobody has the slightest problem believing there is/was a Jewish criminal mafia. There is a Sicilian Mafia. There are Chinese triads, Mexican Cartels, Japanese Yakuza, Russian Mafia, etc.
Everyone easily understands that people with similar worldviews organize to commit crimes of theft, gambling, prostitution, dope, extortion etc and have done so for centuries.
So why is it so -astonishing- that the like minded in the world of the super rich and powerful would organize to gain total power over the US Government and Banking. Yes, there is a Soros cabal, and it is heavily salted with Jewish people out of all proportion to their numbers.
That says nothing about the Jewish man who owns a business I patronize, or about a coworker who is a Jew. They aren’t in on it anymore than your faithful Catholic neighbor is in on what the Vatican is plotting.
But yes, there is a Jewish political “mafia”. Their best protection is those who pretend anyone who points out Soros, Albright, Nuland, Yavonovitch, Vindman, Sonland, Nadler, Schumer, Goldman etc seem to be rather coordinated machine is an anti-semite. Epstein, Wexman, Schwab, etc etc. The SwampBeast is not exclusive to them, but that mafia is a very significant force.
And for extra fun, these animals are rarely if ever observant religious Jews. As Catholic Rudy said, “I’M more Jewish than they are”.
PS.. the best prayer I got after my dad died came from a Rabbi. So no, I am not some kind of Elders of Zion nazi.
Assocation of their ethnic heritage with their leftism is what national socialists do. No excuse for it, including on your part with all due respect.
